  [WGSL] Initial implementation of operator overload resolution
https://bugs.webkit.org/show_bug.cgi?id=251863
rdar://105133289

Reviewed by Myles C. Maxfield.

First pass at adding support for overloaded operators and functions. For now,
only `+` is implemented with 2 operators, and declaring the operations is very
cumbersome, but the patch is fairly large as it is, so more convenient declarations
will follow in a separate patch.

* Source/WebGPU/WGSL/Overload.cpp: Added.
